EU'(`:rli}1\TE S. CARLSEN, OF CHICAGO, ILLINOIS. HAIR-CLIPPER.

To all whom t may concern.'

Be it known that I, EUGENE S. CARLSEN, a citizen of the United States, residing at the city of Chicago, in the county of Cook and 'State of Illinois, have invented certain new and useful Improvements in Hair-Clippers, 0f which the following is a specification.

This invention relates to improvements in a hair clipper or cutter,`and consists in certain peculiarities of the construction, novel arrangement and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The principal object of the invention is to provide a hair clipping or cutting device of such construction and arrangement of its parts that a person may use it for cutting his own hair.

Another object of the invention is to provide a hair clipper or cutter which shall be extremely simple and inexpensive in construction, strong, durable and efficient in operation, with its parts so made and arranged Y as to enable them to be easily assembled or disassembled, for the purpose of repairs or for grinding the knives or cutters.

Still another object is to Vprovide a very simple and efficient means for forming the knives or cutters in the bars therefor. Various other objects and ladvantages of the invention will be disclosed in the subjoined description and explanation.

In the accompanying drawings, which serve to illustrate an embodiment of the invention.

Fig. 9 is a perspective View of a portion of a cutter bar showing a modification in land connected at one of its ends at about its middle to the handle 12, as shown at 14 in Figs-1 to 3, inclusive. .The base or body 13 has its slde edges beveled inwardly and provided witha series of spaced apart and alined knives orcutters` 15 of the ordinary or well-known construction.v The inner surface of the body 13 is by preference flat, as is clearly shown in Fig. 4 of the drawings. At about its middle the base 13 is provided in its outer surface with a countersunk opening 16, in which is located the head 17 of a bolt 18, which is 'screw threaded on its opposite end. Mounted on the inner face of the base 13 is a movable bar or plate 19, which has at each of its side edges spaced apart and alined cutters or knives 20, which are outwardly beveled, but like the knives or cutters .15, have their Specication of Letters Patent. i Patented June 1, 1920, I Application filed March 27, 1919.

inner surfaces flat or straight so as to closely .95

it and freely slide on the inner surfaces Dof the last named knives or cutters. The cutter carrying bar or member19 is provided on its upper surface with anupwardly extended portion 21, thelsides of which form shoulders 22 or guides for the sides 23 of a channeled member 24, which extends longitudinally on the surface of the member 19 adjacent thereto, but is somewhat transversely on the outer surface of the channeled member 24 is a bar 25, which by 1 0 5 Mounted preference is seated in the transversely disposed recess 26, formed in the member 24, and has at each of its ends a comb-like guard 27, each of which is provided with a` series of spaced apart and alined teeth 28, which, as is clearly shown in Fig. 4, are deflected toward the outer ends of the knives 15 and 2O of the base 13 and" cutter bar 19, and are located at their free ends near said knives. Mounted on the outer surface of the bar 25 is a spring 29, which is held in place on the screw bolt 18 by means of a milled nut 30, engaging the screw threaded portion of said bolt.' This bolt is extended through suitable openings in the base 13, movable cutter bar 19, channeled member 24, bar -25, and spring 29, as will be readily understood by reference to Figs. 3

and 4 of the drawings. The cutter bar 19 -is provided with a series of openings 31, through the middle one of which the bolt 18is extended, and through each of the others a pin 32, each of which is riveted at ione of its ends in thebase 13, and has its other end extended into a suitable recess 33,

formed in the inner surface of the channeled member 24. The openings 31 in the cutter bar 19 are longitudinally elongated and in' conjunction with the bolt 18 and pins 32 provide means for the guidance of the cutter bar 19 in its reciprocating move- -ments The end of the cutter bar 19 adjacent-to the stationary handle 12- is provided with a neck` 34, having thereon an vwardl ing o the head 35 is a bolt 36 which is ex. tended through a suitable opening in a proapertured head 35, which is extended outtherefrom. Threaded in the open- -jection 37 on the handle 12 near its uncture with the base 13, and lies in parallelism with said handle, yet at a slight distance therefrom. The head ofthe bolt 36 is4 formed `with a slot 381, in which is movably located an arm 39 o the bell crank lever 40 or other handle of the device, which lever or handle is fulcrumed on an enlarged portion 41 of the stationary handle 12, as shownin Fig. 1 of the drawings. Located between the head of the bolt 36 and the projection 37 and coiled around said bolt is a spring 42, which will cause the handle or lever to be normally held in the position shown A in Fi 1, but will permit itto be moved towar the other handle by gripping the two, thus causing the back and forth movement of the cutter barA 19 on the base or body portion of the device. A guard or i shield 43 of sli htlyV resilient sheet metal is laced over t e head 35, projection 37, an head" of the bolt 36, so as to coversaid parts, and may be frictionally held in position thereon. This shield w1ll prevent thev rounded short arm' 39 of the bell crank lever or handle 40 from being accidentally dislocated from the slot 38 in the head of the the operation of the device.

handles 12 Vand 40`of the device can be` gripped by the right hand, when one side of the clipper can be placed against the persons head or neck and moved upwardly, in which operation the handle 40 may be intermittently pressed toward the handle 12, which will cause the reciprocation of the cutter bar 19 and the clipping or Vcutting of the hair by the knives of said bar and those of the-base on the same side thereof. When thus used it will be {inderstood that theV nut 30 will be located awa from` the head and will not interfere wit After being used with the right hand the-handles 1-2 and 40 may be gripped in the other hand, when, it will be understood, that the opposite side edge of the device will be'placed against the neckAor head of the -user andthe same operation repeated. By using the spring 29 inter osed between the nut 30 and the bar 25 o the comb guard, itis apparent that the pressure of the channeled member 24- -'on the movable cutter a a milled nut 45, which Vrests against one end of a coiled/@spring 46, which spring surrounds an inwardly extended projectlon 47 on the handle 12 at a suitable. point. By this means it is obvious that the tension of the .spring 46 may be regulated by the nut 45,

and that thehandle or lever 40 will be actuated by saidspring in the operation of the' device. In this modification the handle 12 is provided with a base or body 48, which" has on one of its Vside edges`only, spaced aILpart and alined cutters or knives 15 (see v.

ig. 6). Mounted on the inner surface of the base 48 is a spacing member 49 of suitable thiclness to hold a plate 50 of the same size as the base 48 at a' suitable distance.

from said base to receive therebetween the reciprocating knives or cutters. The plate 50 is secured to the base 48 by means of Screws 51, which may be countersunk in said plate. 15 on the base 48 the plate 50-is provided with a series of spaced apart and alined cut- At its side adjacent to the cutters ters or knives-20 of the ordinary or wellknown construction. Located between the base 48` and the plate 50 at their side which is provided with the knives are the movable cutters or knives 52, whichare made of two superimposed bars 53 and 54, which are securedtogether by screws55 and are provided with longitudinal slots 56 for the re ception of pins 57 located in the base 48 and plate 50 for the purpose of co-acting with the slots 56 for yguiding said cutter bars, which are pivotally connected at one of their ends to the handle or lever 40 at the juncture therewith of its shorter arm 58, which arm is pivotally connected to the handle 12 near its junction with the base 48 with which it is provided.

In Fig. 8 is shown another modification in the manner of actuating the bell crank lever or handle 40, which consists in securing a leaf spring 59 at one of its ends to the handle 12 near its juncture with the base which it carries, it being understood that the present modification can be used with either of the above described constructions, although shown only in connection with the construction illustrated in Figs. 5 to 7 inelusive. The spring 59 is exten-ded from the handle 12 so as to rest against the inner surface of the handle 40 so as to actuate it outwardly.

In Fig. 9 is shown a modification in the construction of the knives or cutters which I may employ winstead of the two-piece cutters shown in Figs. 5 to 8 inclusive, and above described, which consists in employing a single movable bar 60 pivotally connected to the spring actuated handle or lever 40 as in the other construction and similarly located.y The cutters or knives 61 of this modification are formed in the bar 60 by drilling spaced apart openings therein from its side edge by means of a drill of-greater cuttingT diameter than the thickness of saidv bar. By this means it is apparent that as.

the drill is centered on a median line between the faces of fthebar 60, and being of greater dimension than the thickness of said bar, it will cut through each of the sides of the bar, thereby forming spaced apart and alined knives or cutters 61 at each side of 'i with the fiat surfaces of which they contact so as to clip or cut the' hair in a very eiicient manner. 1

It is apparent that the cutter bars 53 and 54 may be operativelyl connected to the arm 39 ofx the handle lever 40 by means of the spring actuated screw 36, as shown inFigs:

1 and 3 of the drawings, or-operatively connected to the said lever in the manner 'shown in Figs. 5, 7 and 8 of the drawings.

In order to provide a better hold or gripv on the handle member 12 and l handle lever 70 40each of the sane may be provided with an outwardly extended projection 62 on its ouer surface at proper points between their l en s.

Having thus fully describedmy invention what I claim as new `and' desire to secure by Letters Patent is- 1. In a hair clipper, the combination with a body or base plate having a handle 'member extended from one end thereof and provided with spaced apart knives at one of its side edges and having an apertured projection near said base plate, of a handle lever fulcrumed on thesaid handle near said projection and provided atits inner end with an arm, a bar movably mounted on the base plate and having at its inner portion a projection provided with a screw threaded opening in alinement with the opening in the projection of the said handle member, a headed bolt extended through the opening of the projection on the handle member and adjustably engaging the projection on the movable bar, a spring surrounding said bolt between the head thereof and the projection on the handle member, means on the head of the bolt to engage the arm of the handle lever, said movable bar having knives at one of its side edgesto co-act with the knives of said body or plate.

2. In a hair clipper, the combination with a body or base plate having a handle member extended from one end thereof and provided with spaced apart knives at each of'its side edges, said handle member having 105 an apertured projection near said plate, of
